Irrlicht Engine

(<name> has joined #directx) +1 to rogerborg and long live RAID0 :D Another choice could be DDS textures with DXT n compression (note hybrid saying about patch). These both take less space on disk and in VRAM/RAM, have little impact on performance, but may produce some compression artifacts similar ...

Have you forgotten a "using namespace irr;" line?

<...>my question is, why does it run smooth on other machines while it crashes on mine? So how does the guy who is coding the sound engine on XP suppose to know that his code will not run under vista? Or do we basically have to test the code in both platforms and make sure it runs ok? Also, if it r...

I had a look at the Alpha-to-Covreage example from NVidia SDK (AtoC also available for ATI cards), what it does is like anti-aliasing for transparent textures. I'm just not sure, whether this can be implemented in Irrlicht without updating the engine itself.

Let me guess... sprintf?

Draw a full-screen quad with vertex colors you need and lighting disabled. Turn off Z-buffer as well.

driver->drawVertexPrimitiveList(vertex.const_pointer(),vertex.size(), index.const_pointer(), index.size(),video::EVT_STANDARD,scene::EPT_TRIANGLE_STRIP); TriangleCount is two less than index.size() in tri-strips, mind that. Will I get different results using // T1 T2 T3 T4 IndexBuffer = 0, 1, 5, 4,...

- It has something to do with windows vista 64-bit. If you are running a 64bit version of Max (and you, most probably, are) then it is the problem. Max Plugin is basically a DLL, and you cannot load a 32bit DLL into a 64bit process. So you have to recompile the plugin with Max 9 SDK and targeting a...

Yes, it is possible. If you have a static camera, but you want to rotate the car, you can use a sphere map. You take 1 texture of the environment to be reflected and warp it (I'm quite sure there are plenty programs that do the warp for you). Then you set environment texture as a second texture for ...

I guess to show the desktop, you'd have to take a snapshot of the underlying screen without the window, then draw that as an image/texture in the Irrlicht window background each frame. It'd be pretty much platform specific. A clean way to do it in Windows is calling SetWindowRgn et al., but it is t...

Model a simple ruler in MAX or Blender that has some definite size (for instance, 1 Quatloon :P ). You will have a scene anyway, where you can scale models to fit the dimensions needed. BTW, 3DS has a special tag for defining unit scale and anotehr tag for object matrix that can also have a scaling ...

Try also tesselating tunnel walls. Usually all lighting is per-vertex and then lightness values are interpolated over whole triangle. If a triangle is too stretched, lighting will never be correct.

Click on the icon in the top left corner of console window ("system menu") -> Edit -> Mark, select a region to copy, press Enter.

"switch" under most compilers will generate a jump-table, so after evaluation it will take only one CPU instruction to get to the needed branch.
"if" is hardly optimized at all, so there is a huge chance that every if-condition will be tested.
(actually repeating hybrid)

But this means that the Class1 pointer, even that it points to a data of Class2 it will have the interface of Class1 so if for example Class2 has methodZ and Class1 has methodA your pointer would be able to call only methodA of Class1 or better saying that your pointer will Not be able to call any ...
